cIAP-2/HIAP-1

cIAP2 - balancing cell death and cell survival

The inhibitor of apoptosis proteins (IAPs) are important regulators of cell death and inflammation. The cellular inhibitor of apoptosis protein 2 (cIAP2) contains three Baculovirus IAP repeat (BIR) domains, a Ubiquitin associated (UBA) domain, and a RING domain with E3 ligase activity. cIAP2 inhibits apoptosis through direct inhibition of the pro-apoptotic caspase-3. cIAP2 also regulates cell survival through its role in the tumor necrosis factor alpha (TNF-alpha) signaling pathway.
